20. Using Autonomous Tractors on the Farm with Matt Krueger

We talk with Matt Krueger about his field-level view of autonomous tillage with a 9R series John Deere tractor, from kit installation to dust-driven safety stops, and how better boundaries and AutoPath boost both uptime and data quality. Matt's story centers on labor flexibility, real costs, and where autonomy should expand next. In this special hour-long episode we talk: • autonomy kit details, JDLink Boost connectivity, dual receivers • autonomy-grade boundaries and safe offsets near obstacles • dust sensitivity, camera logic, alerts and overrides • AutoPath benefits for cleaner headlands and data integrity • remote control of depth, pressure and implement settings • ROI framed as uptime and labor flexibility, not replacement • likely next targets for autonomy: sprayers and air seeders • subscription pricing models and reliability trade-offs • NDVI plus as applied maps to trace application misses • skills and fallbacks when GPS degrades or sensors fail With GK Technology, we have a map, and an app, for that! https://gktechinc.com/

19.5 Map The Acidity, Save The Harvest

We dig into why low (acidic) soil pH unlocks aluminum toxicity, how that halts root growth, and which crops suffer first. Then we lay out a practical plan to find acidic patches with smarter sampling, NDVI, and grid-the-zone strategies, and point to lime and buffer pH for the fix. In this episode, we discuss... • soil pH as chemical control and pH level of 7 is neutral • aluminum toxicity risk to crops increases below 6.5 pH • wheat relatively tolerant, legumes struggle with nodulation • stunted roots and thin stands on slopes and sandier spots • acidic areas are patchy and do not always follow productivity maps • importance of using intensive grids and how 0–3 inch sampling in no-till helps detect acidicity issues • soil testing: pair pH with buffer pH to set lime rates • target NDVI-low areas and grid inside zones • variable-rate lime as the remediation path Gridding the Zone with Ag Genesis Part 1: https://www.buzzsprout.com/2297340/episodes/16692855 Gridding the Zone with Ag Gensis Part 2: https://www.buzzsprout.com/2297340/episodes/16692855 Tune in next time for a Tiny Byte of knowledge from GK Technology, where we have a map and an app for that. https://gktechinc.com/

19. Preston Sundeen Pt. 2 - Teaching Precision Ag That Works Today

Welcome back to the second part of our conversation with Preston Sundeen to explore how a two-year ag program prepares students for precision agriculture careers by building real-world skills across hardware, software, GIS, and agronomy. Sundeen's focus is practical confidence: clean data, sound troubleshooting, critical thinking, and learning to ask better questions. We also talk about... • defining precision ag as practical, cross-disciplinary work • balancing agronomy, GIS, hardware and software fundamentals • building file discipline, projections and boundary workflows • sourcing NAIP, PLSS, and satellite imagery effectively • controller setup, CAN bus basics and diagnostics • using simulators to teach certain types of controllers • as-applied data, JD Operation Center, SMS, and FieldView exposure • teaching troubleshooting: manuals, credible videos and tests • digital literacy and AI as time-saving tools • measuring success by momentum, confidence and community impact We had an excellent conversation with Preston and we know you'll enjoy it too.

18.5 Is There a Way to Predict IDC Risk?

We unpack why soybean leaves turn yellow in patches, thanks to soybean IDC (iron deficiency chlorosis) and how to predict IDC risk for management. We share the exact soil tests that matter, how to read the lab results, and where precision mapping saves money and yield thanks to IDC management. We also discuss... • defining iron chlorosis • why iron-rich soils still cause deficiency • limits of testing for DTPA iron alone • three key predictors: pH, EC (salts), and CCE (calcium carbonate equivalent) • why percent CCE beats a simple fizz rating • thresholds where CCE raises severe IDC risk • how residual nitrate can worsen chlorosis • grid versus zone sampling for better maps • using maps to place tolerant varieties and inputs • practical steps to keep beans green Tune in next time for a Tiny Byte of knowledge from GK Technology, where we have a map and an app for that! https://gktechinc.com/

18. Yes, He Mapped The Lawns Too Preston Sundeen Pt. 1

We sit down with Preston Sundean to trace a path from farm kid to precision ag educator and entrepreneur. We dig into teaching ADMS, turning data into fast prescriptions, and why critical thinking matters more than button sequences. In this episode we discuss... • Preston's North Dakota farm roots and agribusiness training • Career moves from ag retail to precision ag education • COVID pivot into entrepreneurship and insurance • Running a classroom like a workplace • The ADMS learning curve and teaching methods • Turning soil tests into fertilizer prescriptions fast • Wireless data transfer and mobile office workflows • Creative ADMS uses for claims and small jobs • Lawn care mapping, NAIP imagery, and bidding • GPS limits, lightbars, foam markers, and as‑applied maps • The case for critical thinking across tools Stick around next week for part two of our conversation with Preston Sundeen.

17.5 Cracking The Code Of Salty Soils

We break down what “salty soil” really means and why salinity and sodicity demand different fixes. We share how to properly diagnose a soil as saline, sodic, or saline/sodic through soil sampling and testing, to avoid turning a manageable patch into concrete. We also discuss.... • defining normal, saline, sodic, saline-sodic with soil test EC and sodium results • why salinity causes drought-like stress without wrecking structure • how sodicity drives clay dispersion and pore collapse • when salts keep clays flocculated in saline-sodic soils • risks of leaching or tiling without a sodicity management plan • sampling depths: 0–6, 6–12, 12–18 inches for diagnosis • using pH as a supporting clue for sodicity • prioritizing amendment before drainage to prevent sodic blowups More information on management of salty soils here: https://www.ndsu.edu/agriculture/extension/publications/managing-saline-soils-north-dakota Tune in next time for a Tiny Byte of knowledge from GK Technology, where we have a map and an app for that. https://gktechinc.com/

17. Variable Rating Herbicides with Kyle Okke Pt. 3

We map residual herbicide rates with field truth, not guesses, turning five-zone soil maps into targeted prescriptions that cut injury and hit weed spawn sites. We weigh OM, pH, texture, and landscape to protect sensitive crops now and keep rotations flexible next year. In this episode we discuss... • base maps from precision soil sampling and scouting knowledge • modded zones for unique poor areas and weed hotspots • organic matter, carbonate, and color as soil clues, not absolutes • extreme pH swings shaping efficacy, injury, and carryover • decision framework from damage mitigation to suppression • variable rates to protect sensitive crops and rotations • SmartFirmer OM layers and controller-friendly rate steps • lidar, soil series, and as‑applied maps to refine zones • practical limits of sensors and when algorithms help • closing insights and where we push rates or back off Missed the first two parts of this episode?

16.5 Calculating Nutrients in Liquid Fertilizer (Bulk Density!)

We unpack why liquid fertilizer math trips people up and discuss how to figure out how to determine pounds of fertilizer in a liquid fertilizer. We talk real examples and show how small liquid fertilizer densities can drastically affect starter outcomes, especially in cold soils. In this Tiny Bytes, we talk • the dry vs liquid mindset shift • how density changes gallons into pounds • where to find pounds per gallon on fertilizer labels • comparing phosphorus from 10-34-0 and 6-24-6 • implications for starter fertilizer in cold springs • simple rules to avoid under or over application Tune in next time for a Tiny Byte of knowledge from GK Technology, where we have a map and an app for that https://gktechinc.com/
